Cold Drawn Steel Wire (GB/T5953-1999)
Cold drawn steel wire (GB/T5953-1999) is a type of wire that is made from cold-drawn steel, often referred to as cold-worked steel or low-temperature drawn steel. The process of cold-drawing involves no heat, but rather a series of mechanical processes to stretch and pull a steel wired piece into shape. This type of wire is used for a variety of applications, including the production of low-tensile strength fasteners, mechanical springs, wire rope and cables, electronics, security systems, automotive parts, eccentrics, and many others.
The primary characteristics of cold drawn steel wire are the uniformity in its dimensions, strength, and hardness. Additionally, it has superior fatigue resistance and ductility. In general, cold-worked wire has a higher yield strength than hot-worked wire. This is due to the increased number of strain-hardened microstructures that are present in the cold drawn wire. The physical properties of cold drawn steel wire are also highly dependent on the amount of cold work that was done during the manufacturing process. As a result of this, it is important to closely monitor the cold work ratio of the wire as it can significantly influence the properties of the end product.
Overall, cold drawn steel wire has advantages when compared to traditional steel wire. For instance, its high fatigue strength, exceptional ductility, and uniformity in its final shape allows for a variety of uses that could not be achieved with the use of traditional hot-worked steel wire. In addition, the process of cold working the wire often results in increased strength and wear resistance.
Due to its high level of strength and wear resistance, cold drawn steel wire is particularly well-suited for applications that require specific tensile strength and wear resistance. For example, it is often used for the production of automotive parts, eccentrics, and mechanical springs as these components generally require wear resistance. In addition, it is also used in the production of fasteners, electronics, mechanical springs, wire ropes and cables, and other applications.
Overall, cold drawn steel wire has a wide variety of uses and can offer a number of unique advantages when compared to traditional steel wire. It is particularly well-suited for the production of low-tensile strength fasteners, mechanical springs, wire rope and cables, electronics, security systems, automotive parts, eccentrics, and many others. Additionally, the process of cold drawing the wire often results in increased strength and wear resistance. As a result, it is an ideal material for applications that require specific tensile strength and wear resistance.
